H3Fa - Omron H3CR-A Manual

Solid-state Timer
DIP Model Timer for PC Board Use
Provides Contact and Solid-state
Output
Four rated times available:
models suffixed -A and -SA: 1 s, 10 s, 1 min, 10 min;
models suffixed -B and -SB: 6 s, 60 s, 6 min, 60 min.
Timer operation may also be controlled through an
external variable resistor.
Timer can be cleaned while mounted on a PC
Board.
Twenty-four-pin IC socket can be used for
mounting the time unit.
Mountable on a 1-inch pitch rack.
Pulse output types also available.
